Where to start

Ok I'm new to the site and to retouching in general however I have used photoshop for some time. Where would be the best place to start to learn simple retouching of face/portrait e.g what things would i do and what order....

1)hide blemishes
2) whiten teeth etc...

and are there any simple to follow tutroials you guys could point me to.

Hi, I'm new too. Just got a tablet for Christmas! So far, I like watching the tutorials on YouTube. There are some good ones on there, as a visual person I feel like I have learned a lot on there. I just joined this site today, so I'm going to check out the tutorials on here too!
